Project description:Type 1 NKT cells play a critical role in controlling the strength and character of adaptive and innate immune responses. Their functional characteristics are distinct from conventional T cells, and are induced by a transcriptional program initiated by positive selection on CD4+CD8+ (double positive, DP) thymocytes. Here we examined transcriptional events in four immature thymic NKT cell subsets in a novel Vα14 TCR transgenic strain bearing greatly expanded numbers of CD24+CD44- NKT cells. We used a transcriptional regulatory network approach to map TCR validation to the transition from DP T to DP NKT cells, and positive selection and lineage commitment to the transition from DP NKT to CD4 NKT

Project description:We report the identification of DN NKT cells developed from DN stage thymocytes. We analyzed the gene expression profiles of NKT cells that have developed from DN stage thymocytes isolated from DP-specific E8III-Cre transgenic Rag2-floxed mouse strain, and NKT cells developed from DP thymocytes sorted as YFP-reporter positive NKT cells that were isolated from E8III-Cre transgenic Rosa26-loxP-STOP-loxP mouse.

Project description:We report the identification of immature thymic CD4(-),CD8(-) double-negative (DN)1e cells with the NKT cell lineage potential. We also analyzed the gene expression profiles of DN1e thymocytes compared with those of mature thymic NKT cell developmental stages termed NKT stage-1, 2, and -3, which are characterized by differential expression levels of NK1.1 and CD44 antigens in C57BL/6J mouse strain.

Project description:Mouse thymocytes can be classified into four major subsets based on expression of CD4 and CD8 co-receptors. CD4-CD8- (double negative, DN) cells become CD4+CD8+ (double positive, DP) cells following productive T cell receptor (TCR) beta chain rearrangement. A small proportion of DP cells are selected through interaction of clonal TCRalpha/beta and MHC self peptide complex expressed on thymic stromal cells. DP cell expressing MHC class I-restricted TCR become CD4-CD8+ cells, which will finally differentiate into cytotoxic T cells, while MHC class II restricted selection generates CD4+CD8- helper lineage T cells. We used microarrays to identify genes important for thymocyte differentiation and lineage determination by profiling gene expression in different thymocyte subsets. Mouse thymocytes were divided into four subsets based on CD4, CD8a, and TCRb expression and purified by flw cytometry. FACS purified DN (CD4-CD8a-TCRb-), DP (CD4+CD8a+), CD4SP (CD4+CD8a-TCRbhi) and CD8SP (CD4-CD8a+TCRbhi) populations were lysed in Trizol, and provided to the Genomics Core Facility of the Memorial Sloan-Kettering Cancer Center (MSKCC) for quality control, quantification, reverse transcription, labeling and hybridization to MOE430A 2.0 microarray chips (Affymetrix). Arrays were scanned per the manufacturer’s specifications for the Affymetrix MOE430v2 chip.

Project description:The lifespan of double-positive (DP) thymocytes is critical for intrathymic development and shaping the peripheral T cell repertoire. However, the molecular mechanisms that control DP thymocyte survival remain poorly understood. Paxbp1 is a conserved nuclear protein that has been reported to play important roles in cell growth and development. Its high expression in T cells suggests a possible role in T cell development. Here, we observed that deletion of Paxbp1 resulted in thymic atrophy in mice lacking Paxbp1 in the early stages of T cell development. Conditional loss of Paxbp1 resulted in fewer CD4+CD8+ DP T cells, CD4 and CD8 single positive (SP) T cells in the thymus, and fewer T cells in the periphery. Meanwhile, Paxbp1 deficiency had limited effects on the CD4-CD8- double negative (DN) or immature single-positive (ISP) cell populations. Instead, we observed a significant increase in the susceptibility of Paxbp1-deficient DP thymocytes to apoptosis. Consistent with this, RNA-Seq analysis revealed a significant enrichment of the apoptotic pathway within differentially expressed genes in Paxbp1-deficient DP cells compared to control DP cells. Together, our results suggest a new function for Paxbp1, which is an important mediator of DP thymocyte survival and critical for proper thymic development.

Project description:T cells develop from progenitors that migrate from the bone marrow into the thymus. Thymocytes are subdivided roughly as being double negative (DN), double positive (DP), or single positive (SP), based on the expression of the CD4 and CD8 coreceptors. The DN stage is heterogeneous and can be subdivided into four distinct subsets in mice based on the expression of CD44 and CD25. In human, three distinct DN stages can be recognized: a CD34+CD38−CD1a− stage that represents the most immature thymic subset and the consecutive CD34+CD38+CD1a− and CD34+CD38+CD1a+ stages. Human DN thymocytes mature via an immature single positive (ISP CD4+) and a DP stage into CD4+ or CD8+ SP T cells that express functional T cell receptors (TCR) and that exit the thymus. In this study, gene expression was measured in each of these nine stages.

Project description:Invariant natural killer T cells (iNKT) cells are innate-like T cells, selected from thymic cortex-resident CD4+CD8+ double positive (DP) thymocytes. Despite major advances in the understanding of iNKT cells development, the heterogeneity of iNKT subsets and underlying molecular programs that guide iNKT cell-lineage remain unclear.
